The current standard of PIM testing offers a well-known system of two primary carriers and a calculated PIM frequency, which is monitored via a spectrum analyzer. This provides a measurement of the overall linearity of the antenna system and the surrounding environment.

The Distance-to-PIM test is simple, immediate, and accurate. DTP informs the technician of the distance and magnitude of all the PIM sources simultaneously, both inside the antenna system and beyond the antenna.
